Cohabitation Likes/Dislikes Issue?

[LialaOkami]

Allosaurus and Metriacanthosaurus both state in their description that they like each other and benefit from being in an enclosure together. However, when I cohabbed the two species (two of each), they instantly fought and both Metriacanthosaurus's were killed in the combat. What is the point of the social like/dislike mechanic if the dinosaurs' behavior directly counteracts it?

maybe they don’t have enough space/territory in your enclosure or you have to add more goats and meat.

Also: If you have carnivores with an Aggressive disposition then they'll be an ♥♥♥♥♥♥♥ and pick fights with other animals.

never mixed any carnivores besides medium/large with compies but i think they need traits like docile or tolerant to get along even if they "like" each other
